Question

Examlex · Accepted Answer

The Answer is ANOVA requires assumptions that the m groups or factor levels being studied represent populations whose outcome measures:
•are randomly and independently obtained,
•are normally distributed, and
•have equal variances.
If these assumptions are violated, then the level of significance and the power of the test can be affected.If sample sizes are equal, violation of the third assumption does not have serious effects on the statistical conclusions; however, with unequal sample sizes, it can.A nonparametric test may be used when the assumptions underlying ANOVA are violated.
